    Abstract: The supply of power from a battery to a load is controlled by the charging current output status of a solar cell, such that when the solar cell receives light, the load is cut off; and once the solar cell no longer receives light, the battery is charged to a preset saturation level and the solar cell no longer supplies charging current to the battery, or the charging current falls short of a predetermined level, the battery will revert to an output mode with suspension of the charging function.

  • Patent number: 6372978
    Abstract: The present invention is a self-contained, solar powered heating and cooling system for a building. The collector has an insulated heating chamber, and a light transmissive cover and a thermostatically controlled vent. The chamber contains absorptive columns standing on the floor. An internal liquid conduit exposes the liquid to the heat within the chamber. The collector is connected to a remote thermal reservoir such that a liquid circuit and a separate gas circuit both circulate heated fluid to the reservoir. Heat can be stored in any of a liquid reservoir, thermal mass reservoir and gas reservoir. Wind powered generators and photovoltaic cells provide power for the system or other applications. The thermal reservoir has heat exchangers which deliver stored heat to the building or operate a heat operated refrigeration machine (e.g., a liquid absorption chiller). Additional self sustaining power sources may optionally be incorporated into the present invention.

  • Publication number: 20010054252
    Abstract: A light element with a translucent surface includes an energy converter, wherein the translucent surface is so formed as to direct only that portion of the radiation onto the energy converter that impinges on the translucent surface. The energy converter may be a solar cell, a fluid line or a light guide. The light element is particularly suited for illuminating interior spaces with diffuse light.

  • Patent number: 6313391
    Abstract: A solar powered electricity generating system comprised of a concentrator assembly that concentrates solar flux into a thermal storage unit. The thermal storage unit converts solar energy into heat energy which is then provided to three cascaded converter stages which, in the preferred embodiment, are comprised of a thermionic electric converter (TEC), an alkaline metal thermal to electric converter (AMTEC) and a thermoelectric generator stage comprised of a plurality of thermal photovoltaic cells. A phase change material is positioned within the thermal receiver such that the solar flux converts the material from a solid phase into a liquid phase such that the thermal storage unit can continue to generate heat energy when the sun is no longer providing thermal flux to the receiver as a result of the heat energy produced as the phase change material changes back from a liquid phase to a solid phase.

  • Patent number: 6244062
    Abstract: A solar collector system for converting solar radiation to thermal energy and electricity has an upper cover with a material that is transparent to solar radiation. A solar energy absorbing structure is disposed under the upper cover and has a heat conducting material such as metal. In addition, a first heat transfer system is disposed in contact with the solar energy absorbing structure and has a material that transfers heat from the solar energy absorbing structure to a first substance flowing within the first heat transfer system. The solar collector system also has electric cells that absorb solar radiation and convert it into electricity. The cells are configured and disposed on at least a portion of the upper cover.

  • Patent number: 6162985
    Abstract: This invention is a thermoelectric-photovoltaic device for converting electrical energy from both thermal radiation and sunlight. Thermoelectric energy is produced from thermoelectric cells when a temperature difference is present between two different semiconductor materials. Photovoltaic energy is produced from photovoltaic cells when two different semiconductor materials are exposed to sunlight. To achieve increased electrical energy production, one of the semiconductor materials is placed in a cell having a reduced pressure atmosphere to increase the radiative energy thermal exchange with the black sky at night.

  • Patent number: 6130377
    Abstract: A thermoelectric battery is disclosed which uses pipes connected in series made from two different metallic materials. The pipes are connected in an alternating manner and exposed to sunlight to increase the temperature therein. Other parts of the pipes are connected to a cooler temperature such as water or the ground to produce a temperature differential suitable to produce a voltage potential. The thermoelectric battery is also used to supply power to a swinging pendulum in which two different ionic chemicals are mixed at a selected time to generate electrical power. The thermoelectric battery, connected through a pacemaker circuit, produces a magnetic field at predetermined periods equal to a multiple of the period of oscillation of the pendulum, the field acting to give the pendulum a push in order to keep the pendulum from stopping.
